;TO ALL WHOM IT MAY CONCERN:

Be it known that we, A. H. NATHANS and MATTHEW THORNTON, of Macon, inthe county' of Bibb; and State of Georgia, have invented a new andimproved Oar-Axle Box; and we do hereby declare the followin g to bea'full, clear, and exact description oil the same, sufiicient to enablethose skilled in the artt'o which our invention appertains to make useof it,*reference being had to the' accompanying. drawings, forming partof this specification, in whichi I Figure 1 is a longitudinal verticalsection of the axle-box, and

Figure 2, a perspective view of the packing-plate 0,- showing theparticular feature'n'hich constitutes our invention.

This invention is an improvement upon the axle-box patented by D.H..Dotterer, April 3, 1866, and coin sists in so constructing the springpacking-plate, used in his invention, that the oil cannot escape fromthe box, (whereby the value of the whole device isgreatly enhanced.

In the drawings, A A represent the walls of the axle-box, and B the endof the car-axle in position in the box. 0 is the metallic springpackingplate, that fits aroundthe axle,justwithin the inner side of thebox, to prevent the entranceof dust, &c. In the aide-box referred to,upon which this is an improvement, the plate 0 operates between a lowpartition, I), and, the inner wall of the box. It is found inpractice,however, that the oil in the reservoir, E, will slop over the partitionD, and, penetrating under and, around the packing-plate G, will rise tothe opening, G, in the inner wall of the box, in which the axle works,and will thence escape in large quantities, rendering the box anexpensive one to use. I

To obviate this dei'ect, we construct the metallic packing-plate C witha curved packing, c, the ends of which rise above the ends of thepartition D. i This packing may be either on the inner or outer side ofthe plate C. If on the inner side, it operates against the outer wall ofthe partition D, and prevents the oil from working down under the plate0 at all. If on the outer side, it operates against the inner side ofthe wall A, and prevents the oil which may slopover the partition D fromrising between the wall A and plate C far enough to escape at theopening G.

Upon whichever side of the plate O it maybe used, it prevents all escapeof the-oil under the plate, thereby rendering the box much moreeconomical than before, besides keeping the axle better lubricated, andcausing the whole apparatus to work with increased eth'ciency.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent,is

The curved packing 0, when arranged on the side of the plate Q, in themanner andfor the purposes specified.

MATTHEW THORNTON.
